RSL10-SOLARSENS-GEVK: Solar Powered BlueTooth Multi−Sensor Platform

The RSL10 Solar Cell Multi−Sensor Platform (RSL10−SOLARSENS−GEVK) is a comprehensive development platform for battery−free IoT applications for smart building, smart home, and Industry 4.0 verticals. Based on the industry’s lowest power Bluetooth® Low Energy radio (RSL10), the board features sensors for environmental and motion sensing (BMA400−a smart 3−axis accelerometer, BME280− a smart environmental sensor, and the NCT203 wide−range digital temperature sensor).

The board also features a low weight, low profile 100µF storage capacitor of; a programming and debug interface; and a connected solar cell.

Since the device harvests energy from a low current source, it is important to minimize leakage of the overall system during operation and standby. Along with other energy efficient devices, an ultra−low quiescent current LDO (NCP170) on the board significantly minimize leakage.
